You'd combine them on the server; instead of fetching data FROM [tax] and FROM [products], you JOIN them.

If you're determined not to use the server to do this, you'd have to create a new DataTable that contained the matching results from both sets, or use the techniques outlined here[^].

converting database schema in form of schema graph having primary and foreign key relationship and storing in cache using datastructure........?????????

Just throwing question marks at a sentence doesn't make this a question. What are you asking, and what have you written so far?

Visual Studio has tools where a table can be viewed as a schema diagram - if that is what you are looking for.

hey guys i'm making a ladder and snake game using C# and i'm stuck at the point where i need to move my players forward .. which means that the players move correctly only in round 1 but after that they start going backwards .
for example for player one the first turn the dice showed number 4 so it moved to square 4 , in second round the dice showed number 2 the player goes back to number two and not to number 6 as it's suppose to .. so can you help me with that i would really appreciate it
this is my code so far :

Your code needs to be formatted, click on Edit to make changes and then click on the format bar above the edit box and select code, and scroll down the list to select the programming language. Then move all your code inbetween the <pre > tags. </pre>

this program I am do it but there is an error into it ,the error is in the function ...gotoxy().the massege error is "gotoxy is undeclarated"...I am do this program by Visual Stadiue 2006...
the code:
#include<iostream.h>
class base
{private:
int n,i,j,h,x[10];
float fx[10][10];
static char c;
public:
void set(int cn,int ci,int cj,int ch,int cx,float cfx,char cc)
{
cn=n;ci=i;cj=j;ch=h;cx=x[10];cfx=fx[10][10];cc=c;
}
void show()
{cout<<"\n\t\t******\t THE DIFFREEN\t******";
cout<<"\n\n";
cout<<"\n ENTER THE NUMBER OF THE VALUSE OF X:";
cin>>n;
cout<<"\n\n ENTER THE FIRST VALUE OF X1:";
cin>>x[0];
cout<<"\n ENTER THE INTERVAL:";

}}
};

k.show();
}

There are lots of mistakes.
for () {
and };
but fixing these won't make the other errors go away.
Your biggest problems are text layout. indent (3 or 4 spaces from the left edge)
for () {
doSomething();
a = b+c;
};
it helps if you create both open{ and closing braces }; at the same time and insert code between.

1) That's not C#, so you are in the incorrect forum
2) I don't think VC++ has any gotoxy(int, int) method in the libraries so you will probably need to make your own, see this:
http://www.cplusplus.com/forum/beginner/28859/[^]
If you think you can do a thing or think you can't do a thing, you're right - Henry Ford

Either you havent created a method call "gotoxy()" or you haven't included a library file (.h or .cpp) that contains the "gotoxy()" method.
Think! Don't write a line of code unless you absolutely need to.

im starting my work with c# and i have a problem with inheritance, i need one form to inherite after another one, it wouldnt be a problem but dialog class inherit after "Form", since in c# its only one inherit per class and dialog class cant run whitout "Form". how can i implement my own class into dialog class?
(sorry for my bad english)
|
|
|
|
|
I'm sorry, but I'm having trouble visualising what you are trying to do here. Could you show what you're trying to have as the inheritance chain?
|
|
|
|
|
i've made a variable
using /some headers/
namespace Project1
public partial class profil : Form
{
Rycerz gracz = new Rycerz();
/rest of code/
the wariable called gracz of class Rycerz, created in winform, i need to use this variable in other winform how can i inherit this in the other winform?
i hope its better now?
|
|
|
|
|
Okay, that's not inheritance. What you would be looking to do is either make this a public property or public field and have the other form access that if necessary. Now, if your other form is opened by this one, a better method would be to raise an event back to this form, and set the values based off that event. That way you stop the other form having to know about Rycerz.
|
|
|
|
|
well i dont understand exatly what you mean, make the variable gracz public? how do i make the other form to access it (i made variable public but still other form cant see it)? sorry for such noob questions.

I think you want something like this:
public class Child : System.Windows.Forms.Form
{
private int _privateField = 0;
public int PublicProperty
{
get { return(_privateField); }
set { _privateField = value; }
}
}
public class Parent : System.Windows.Forms.Form
{
private void SomeMethod
{
Child child = new Child();
child.PublicProperty = 42;
child.ShowDialog();
int processedValue = child.PublicProperty;
child.Dispose();
}
}
In the parent form, you create an instance of the child form and pass the initial integer value to it via its public property. The child form can then work with it in every way you can think of.
ShowDialog() is a blocking call. It returns when the child form closes. You can then still read from it until it is disposed. That way you can get the changed value of PublicProperty.
You can as well create multiple public properties. That could be necessary if child form's processing results in a value of different type than the input.

You form would not inherit from form but would inherit from your base form. I THINK that's what you're trying to do. It's not clear at all.
A class can inherit from only one other base class, but that base class can itself inherit from some other class, like System.Windows.Form.
|
|
|
|
|
i will state it other way, i have a variable created in one form i need to use it in other form how can do that?
|
|
|
|
|
Make a public Property that returns the value.
|
|
|
|
|
You can make your own Dialog Form instead of trying to inherit from the existing class.
Or easier, your form can inherit from the Dialog class.

Hey guys,
I have this weird problem, when I want to open the FolderBrowserDialog, I can't select any folder on my phone! When I want to select a folder on my local HDD, there's no problem, but when it comes to the phone the select button get's deactivated and I can't select a folder. (see attached picture)
Here's the code I'm using:
private void button3_Click(object sender, EventArgs e)
{
using (FolderBrowserDialog dialog = new FolderBrowserDialog())
{
dialog.Description = "Open Folder";
dialog.ShowNewFolderButton = true;
dialog.RootFolder = Environment.SpecialFolder.MyComputer;
if (dialog.ShowDialog() == DialogResult.OK)
{
textBox2.Text = dialog.SelectedPath;
}
}
}
What I want to do is copying my music to the phone, but therefore I need a path.
When I open the phone with Microsoft Explorer, the path is shown such as "Computer\GT-I9300\Card\Bluetooth" (that's the folder "Bluetooth" on the root of the external card of the phone). So there's no explicit path either! Is there any other way to get the path? Programs such as WinAmp or WMP can connect to the phone to copy files without any problems, so it must be possible somehow.
